Role

Macronutrients

Nitrogen

 , and  in some cases

  • Required by all metabolically active cells

  • Constitutes proteins, nucleic acids, vitamins, and hormones

Phosphorus

( or )

  • Constitutes cell membranes, proteins, all nucleic acids, and nucleotides

  • Required for phosphorylation reaction

Potassium

K+

  • Required in abundance by meristematic tissues

  • Maintains anion-cation balance in cells

  • Involved in protein synthesis and activation of enzymes

  • Involved in opening and closing of stomata

  • Maintains turgidity of cells

Calcium

Ca2+

  • Synthesis of middle lamella (Ca pectate) of cell wall during cell division

  • Formation of mitotic spindle

  • Proper functioning of cell membranes

  • Activates enzymes; help in regulating metabolism

Magnesium

Mg2+

  • DNA and RNA synthesis

  • Constitutes ring structure of chlorophyll

  • Maintains ribosome structure

  • Activates enzymes of respiration and photosynthesis

Sulphur

  • Constitutes several coenzymes, vitamins (thiamine, biotin), and ferredoxin

  • Found in amino acid cysteine and methionine
